I don't think that's an improvement, please let's not add more obscure environment variables. You should try to use the user backend when the X display is available and fall back to curses otherwise. -- Alexandre Julliard julliard(a)winehq.org

Re: riched20: new selection invalidation logic

Could you explain why you adding asserts everywhere (only 11 in this patch alone!!!)? Instead of using proper error handling? For the past year or more that was the main source of user problems. And if you could how many installers have been broken with this technique, you will probably account for 90% of all the installers that otherwise would work on Wine. Have you even tried your code on purposely broken rtf? How does it handle it? Vitaliy Margolen

Re: msvcrt: In text mode a ctrl-z signals EOF
by Duane Clark 08 Aug '06

Duane Clark wrote: > Changelog: In text mode a ctrl-z signals EOF > Spotted by David Hagood with test suggested by Dan Kegel > Howdy David. Any chance you could try out this patch? I added a conformance test, as suggested by Dan, and it looks like any data after a ctrl-z is stripped. Of course, it may be that in the real world there will never be anything other than additional ctrl-z characters, in which case your version would be fine (and more efficient). http://www.winehq.org/pipermail/wine-patches/2006-August/029544.html

Why do you print and free a NULL structure? And why do you assign it to analysis and then overwrite it right away with a new allocation? -- Alexandre Julliard julliard(a)winehq.org

Re: winhelp: bug fix in LZ77 decompressor - prehistory to make things clear

I try to explain why memcpy worked before. It did not worked. As far as I noticed, this bug does not affect small files (<=0x1000) but if file was large enough (>0x1000 byte) - it will appear. In my case it was multi-colour metafile (jwpce.hlp, http://www.physics.ucla.edu/~grosenth/jwpce.html - lots of metafiles). Small pictures are OK, but large are jammed. What is interesting, the bug affected bitmap part of metafile, so no errors while PlayMetaFile, but the result bitmap was jammed a little. --HolyLich

LZ77 decompress algorithms needs copiing byte-by-byte - of course, if areas overlap, then dest area WILL NOT match the src area before. It IS correct for LZ77! The simpliest version of memcpy routine, like this: void my_memcpy(char *dst, char *src, int len) { while (len-->0) *dst++=*src++; ) WILL work correctly for LZ77. memcpy provided by gcc is optimized - it NOT copies byte-by-byte from beginning till end. If you mediate over lz77 decompress algo (dlls/kernel/lzexpand.c) the things will be clean.
